Killian's dehiscence
Killian's dehiscence (also known as Killian's triangle) is a triangular area in the wall of the pharynx between the cricopharyngeus and thyropharyngeus which are the two parts of the inferior constrictors(also see Pharyngeal pouch). It can be seen as a locus minoris resistentiae. Similar triangular area between circular fibres of cricopharyngeus and longitudinal fibres of esophagus is Lamier's triangle or Lamier-hackermann's area.

gollark: It could just be that the extremes are more visible.
gollark: Apparently, because some unspecified event had occurred two years in a row at the same time for them (???) and because it's "comforting".
gollark: Also people just not caring about truth for some reason. A mere 1.8ish hours ago someone was telling me about why they believed in astrology.
